ELECTRIC GAS-LIGHTING ATTACHMENT'FOR BU RGLAR-ALABMSQ SPECIFICATION formngpart'of Letters Patent No. 292,786, dated February 5, 1884.

` Application filed July 17, 1883. (No model.)

To a/ZZ whom, it may concern.-

Beit known that I, A. LIVINGSTON Boennr, of Jamaica, in the county of Queens and State of New York, have invented an Improved Electric Gas-Lighting Attachment for Burglar- Alarms; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to yan improvement in apparatus to be used in connection with burglar-alarms for the purpose of ,automatically turning on and igniting'` one or more gas- I 5 jets whenever the burglar-alarm bell is sounded or the indicator-drop falls; but it may also be employed for other analogous purposes. In the several apparatus heretofore used for this purpose the usual method has been to put the burner andthe burglar-alarm in multiple are from the same battery,l so that the closing of the circuit at a door or a window would operate both the burner .or burnersand the burglar alarm simultaneously; or the indicator-drop in falling would shunt part of the current through the burner to be lighted; or

in another form of apparatus the indicator` drop in falling would throw an independent battery upon the burner-circuit. In either of the first-mentioned cases-that is, where a single battery is employed for the two purposes-th ere is always a possibility ofthe current being so weakened byv theI division that either the burglar-alarm or vthe burner will fail to operate at all, or will operate imperfectly--as, for instance, the gas may be partially turned on but not ignited; and in theV last mentioned case-that is, where two batteries are employed-there is danger that in the excitement and confusion the burner-batthat the circuits are not weakened'by div'ida ing them, and the burners, after having been successively lighted, are automatically cut out.

of circuit. In my said inventiony either one drop to fall, then open the burglar-alarm cir"v cuit and switch the battery successively to one .or more gas-burners to light the same, and

then again throw the current upon the burglar-alarm circuit to sound a continuous alarm;` or, as a modification thereof, will', when the' burglar-alarm circuit is closed, first throw a special battery successively into and out of circuit with one or more burners and then cut itself out of the burglar-alarm circuit; and

it further consists in certain novel construc-4 tions and combinations of parts, as hereinafter particularly set forth.

In the accompanying drawings, Figure l! represents my improved apparatus as operated by one battery only, and Fig. 2 represents the same as used in 'connection with two bat- A may represent any suitable support toV which my improvedv apparatus is attached, and E the frame of a clock-Work ,Q by which the mechanism hereinafter described isA driven.

A is a lever afixedto the shaft C of lthe clo cli-work.

Upon the shaft C is secured a ratchet-wheel,

B, havingtwo or more teeth, and upon said-v shaft is also secured a coiled spring, D, one

end of which is secured to said shaft and its other end to the frame E. A toothed wheel,

F, is tted loosely upon said shaft 0, and provided with apawl, G, which engages with the ratchet-wheel B, andvprovided also with pins the ratchet-wheel B. The Wheel F drives a H, equal in number to the number of teeth on pinion and escape-wheel, I, with its verge J,

from which latter is suspended a pendulum, O.

K is an electromagnet', the armature of which is pivoted at m, andI is providedwitha stop-pimN, which, when vthe. armature is in,A its normal position, (or off the magnet,) engages the pendulum O, and thus prevents the clock-movement from running, and when the armature is attracted to the magnet said pin N is released from the pendulum and the clockwork is started.

l) is a spring, the upper end of which extends upward to engage with the free end 'of the lever A, and on that part of said spring which is opposite to the end of the armature L is formed a catch,' Q, which, when said armature is attracted and the upper end of the spring freed from the lever A, projects over the end of the armature and prevents the pin N from stopping the clockwork until the spring P is again pushed back by the lever A.

S is a spring, against which the lever A abuts when the apparatus is set at otff and Ta similar spring, against which said lever abuts when the apparatus is set at 011. Both these springs are insulated.

The electric connections arc as follows: Referring to Fig. l, U is the battery, from one pole of which a wire is connected in the usual manner with the several door and window springs used in burglanalarm work, as at V, and from its other pole t-he wire cis connected to the frame of the clock-work. The burglaralarm bell (land its indicator are connected by the wire blirst with the insulated spring S, thence by wire c with the electro-magnet K, and thence by wire c with the insulated spring T.

l and 2 are thc gas-burners to be lighted, and are ofthe kind known as vibrators or automatic gas-burners. Any desired num ber ofthese may be used, and they are connected, respectively, by wires f j', with insulated springs X Y, each having its separate spring and wire connection. The said springs are placed ont of contact with the wheel F, but in such position that when said wheel rotates (in the direction of the arrow) the pins H H will come successively in contact with them; and said springs are bent, so that each will make two or more contacts with the pins as they pass the same to insure the lighting of the burners.

V is a spark coil,H connected to the ground and to that pole ofthe battery which is opposite to the one connected to the frame of the clockwork.

In order to indicate more clearly the several circuits, the wires which forni the burglaralarm circuit are shown in full lines, and those which form the burner-circuits are shown by dotted lines. y

The operation is as follows To set the apparatus, the end of the leverAis set to on and in Contact with the spring T, the ratchet B engaging with the pawl G and holding it,

and the upper end of the spring P being now released from the lever A, the catch Q rests against the end of the armature L, as shown. Now, should the burglaralarm circuit be closed at V, the current will pass from the battery U by wire yn, connection V, wire a", indicator-magnetdt, bell-magnet d, thence by wires b and c to magnet K, thence by wire c and spring T, through the lever A and frame of clockwork.to wire a and back to battery U, the result being that the indicator-drop r will fall, the bell d be rung, and the armature L of the magnet X attracted, and thereby the pin N will be withdrawn from the escapement J and the clock-work set in motion by the force of the coiled spring, so that the lever A will begin to move toward the spring S. As soon as the lever moves out of Contact with T the circuit is broken and the current cut oi from the burglar-alarm and from the magnet K; but the catch Q has in the meantime passed over the end of the armature and prevents the pin N from stopping the clock-work; and hence the level' A continues its movement toward S, and during its onward movement the pin H is brought in contact with the spring X, and the current then ilows from the ground 7 through the coil \V, battery U, wire (d, (shown by dotted line,) frame of clock-work, pin H, and spring X, (which make one or more contacts,) and by wire j" to burner l, and thence to the gas-pipe and ground, lighting said burner. In the further onward movement of lever A and wheel F the pin H` passes out of contact with X and comes in contact with Y, thereby igniting the gas at burner 2, and' then passes out ot' contact with Y. XV hen said lever A, in its continued movement, makes contact with the spring S, the magnet K is shunted out of circuit, the burglar-alarm circuit then being made from wire a, lever A, and' spring S to wire b, as before. Wvhen the lever A arrives at S, it pushes back the upper end of the sp ring P and withdraws the catch Q from the armature L, which latter is then retracted by thc spring i, when the pin N again stops the clockwork by coming in contact with the pendulum O but the burglar-alarm circuit being still closed, either through the closed connection at V or through the shunt closed by the falling of the indicator-drop, the bell will continue to ring until both these connections are broken.

I do not confine myself to the exact forms of mechanism herein shown and described, as it is obvious that the same may be modified or changed without departing from the principles of my invention, the object being to construct the same so that when the burglar-alarm circuit is closed at a door or window and the rst alarm sounded it will operate automatically to iirst cut off the burglar-alarm circuit, then switch the battery successively to the several gas-burners to ignite the same, cutting out each burner as soon as lighted, and then again throw the current upon the burglar-alarm circuit to sound a continuous alarm, so that no two circuits shall be closed at the same time.

In the modification shown in Fig. 2 no change is made in the construction of the apparatus, except that the end of the lever Ais covered with insulating material and the springs S and T are brought together, but not in contact with IOO.

each other until brought into contact by-the leverAon its arriving at ofi77 as will be presently described. In this case, as in the former, the lever A, being set at 013, is retained in that position by the ratchet and pawl, and the catch Q rests against the end of the armature L. The burglar-alarm circuit is from one pole of the battery U, the wire a, connection V, wire n', to the alarm-instrument; thence by wire b, spring S, and wire cto magnet K; thence by wire e and lever A through frame of clocl work, and by wire a back to the battery U, the lever Abeing set at on,7 and the contact between the springs S and T being broken. When this circuit isv closed at V, (the lever A being set at on, 7) the armature L is attracted, the catch Q passes 'over the end of the same, pin N is withdrawn, releasing the clock-work, and the lever` A begins to move toward the springs S and T. When'the pin H makes contact with the springs X and Y, respectively, a separate battery, U', is turned upon the automatic burners 1 2, the circuit being from the ground through the spark-coil W and battery U; thence to the frame of the clock-work and pin H; thence through whichever ofthefsprings X Ywith which said pin is in contact, by one of the wiresf, tothe burner attached to said wire to ignite said burner. The burners are thus successively brought into and thrown out of circuit, asin the former case; but the burglar-alarm circuit remains closed meanwhile,

either through the connection at V or through the shunt m', closed by the falling of the indicator-drop. Vhen the lever A arrives at S, it brings the latter into contact -with T, thus shunting the magnet K out of circuit, and at the same times pushes back the spring I, thereby withdrawing the catch Q and stopping the clock-work, the newly-formed burglar-alarm circuit still remaining closed.

What I claim as my invention is- 1. An electric gas-lighting attachment for burglar alarms, consisting of an automatic switch, A, constructed as described, and operated by a clock-work mechanism, which is set in motion and stopped by the armature of an electro-magnet, K, in the'manner set forth,

and is provided with a series of circuit-closers feres with the action of any other oi-said circuits, and each burner is ignited separately,

and immediately thereafter is cut out of circuit, as set forth.

2. An electric burglar-alarm and gas-light` ing apparatus composed of thefollowing parts in combination-namely, the automatic switch A, constructed and operated by clock work mechanism, as described, the escapement I, an d pendulum O, the armature L, provided with the stop-pin N, a burglar-alarm instrument,

the springs S and T, and the burglar-alarm circuit and separate gas-burner' circuits, including the circuit-closers H and X Y, the whole constructed and operating, as described, to first sound the alarm, then to divert the current to each burner successively, and then to divert the current again to the ,burglar alarm for the purpose of effecting a continuous alarm after the last burner-circuit has been made and broken.

3. The combination, with the magnet K and itsarmature L, lever A, spring D, and train of clock-work, of the catch Q, mounted upon the spring I), as shown and described, for the purpose set forth.

y4. The burglaralarm and switch-circuit, composed of the battery U, wire a, clock-work frame E, lever A, spring T, wire e, magnet K, wire c, spring S,and burglar-alarm instrument, as shown and described.
